<p>there's no obvious definition for normalization in the Reference, but <a href="https://github.com/rust-lang/rfcs/blob/master/text/2093-infer-outlives.md">https://github.com/rust-lang/rfcs/blob/master/text/2093-infer-outlives.md</a> makes reference to it. i'm guessing it has to do with fully resolving the concrete type of an associated type of a trait? the term mostly seems to appear in compiler internals.</p>

<p>yes, it's not supposed to be user-visible</p>

<p>thanks. i think the main user-visible consequence in the context of RFC 2093 is that certain outlives requirements that could be inferred on associated types are not, so they still have to be explicitly specified</p>
